Proper billing for multiple procedures

Do not use the same CPT code billed on multiple lines for the same date of service, instead use one line with multiple units. If there are multiple dates of service, each line should be billed separately.

The following are examples for billing a pathology exam on three breast biopsy specimens on the same date of service:

Correct way: One line with the CPT code and three units

Wrong way: Three lines with the CPT code with one unit each

If the claim includes three lines with one unit for each line on the same date of service, the additional lines appear as duplicates causing the additional lines to deny.
